Noam Chomsky to Speak at Fermilab's Colloquium on October 8

Noam Chomsky

The word is out. On October 8, Noam Chomsky will speak at Fermilab's colloquium at 4:00 p.m. in Ramsey Auditorium. Known as the father of linguistics, Chomsky is considered to be one of the leading intellectuals of the 20th century. Also known as a political dissident, Chomsky's talk, "The Aftermath of September 11," will focus on his book, 9-11. "I invited Chomsky to speak at Fermilab in February 2002. He immediately accepted, but he wasn't available until 2003," said Rajendran Raja, who will be hosting Chomsky at Fermilab. "He has definite views about politics, and his book, 9-11, is very provocative. It goes beyond the "us vs. them" and takes a global view." Because Chomsky is expected to draw a very large crowd, the colloquium will be in the auditorium. There will be overflow seating in One West, and streaming video will be available online at a later date. Non-Fermilab employees are welcome to attend the colloquium, but they must enter the site through the Pine Street entrance.

Sloan Digital Sky Survey Meets at Fermilab 10/2-10/4
SDSS logo

The Universe is coming to Fermilab! For five years, the Sloan Digital Sky Survey (SDSS), a collaboration of 200 scientists from participating institutions, has been scanning the heavens from a telescope site in New Mexico. Their goal: a 15-terabyte map of half the northern celestial hemisphere. The data will illuminate the birth of galaxies, the nature of dark matter, and the evolution of the universe.

The collaboration's semi-annual meeting takes place at Fermilab on October 2-4. About 100 members are attending to discuss recent research using Sloan data. The keynote talk will be held on Friday at 5:30 by Steve Majewski of The University of Virginia, an expert in the field of galactic structures. Most of the talks will take place in One West, and all are open to the public.
Agenda

Illinois schools doing preliminary work for future supercollider
By Sandra Guy
Researchers are working to create technology they hope will pave the way for a next-generation particle accelerator to be built in northern Illinois.

The effort, led by the Illinois Consortium for Accelerator Research, is a long-term one. The U.S. Department of Energy's Office of Science could take three to 10 years to decide on a site.

CDF Observes Mystery Meson

$CDF's J/psi - pi\sup{+} - pi\sup{-} mass distribution, with the large left peak being the well known c-cbar meson psi(2S), and the small bump on the right the new mystery particle X(3872).$

CDF's J/psi pi pi mass distribution revealing a mystery particle X(3872) by the small bump on the right; the sharp peak at left is a well-known charmonium landmark called psi(2S).

Mesons are bound quark-antiquark (q-qbar) pairs. The simplicity of charmed mesons (c-cbar) could bring clarity to the unexplained "surplus" of light mesons, observed particles that don't seem to fit the predictions of the simple quark model. At the Lepton-Photon Symposium at Fermilab in August, the Belle collaboration (KEK, Japan) announced the discovery of a new meson weighing around 3872 MeV. It decays into a c-cbar meson, called J/psi, and two pions. Named X(3872), the particle could be just another not-yet-observed c-cbar state. But observations from Belle instead suggest the particle might be a four-quark "molecule" (c\bar{u}-u\bar{c}), an exotic combination allowed by theory but never so far observed.

With over 200 inverse picobarns of Run II data now on tape, CDF experimenters quickly searched for the new particle and confirmed Belle's observation, announcing their findings at last month's Quarkonium Workshop at Fermilab. The Tevatron's different vantage point offers new insights.

"In Belle, we have been working hard to understand this new, narrow charmonium- like particle," said the University of Hawaii's Steve Olsen, a Belle charmonium hunter. "We were pleased to learn that CDF confirms this state with a mass value that agrees with our measurement. Detailed comparisons of the production in e+e- and p-pbar collisions may help to sort out this intriguing puzzle."

According to theorist Kuang-Ta Chao, Beijing, the large rate observed by CDF supports the conventional interpretation of X(3872). Whether exotic new particle or mischievous imposter, X(3872) is an auspicious omen for future studies at the Tevatron.

Fermilab budget
Lacking an Energy Appropriations Bill for FY2004, all Fermilab spending is subject to a Continuing Resolution that authorizes spending under FY2003 terms and conditions until October 31. The Continuing Resolution does not allow the initiation of new activities.

URA Scholarship Information
Universities Research Association, Inc. (URA) offers a number of four-year scholarships to children of regular full-time employees of Fermilab. The scholarship award will be continued for a maximum of four years providing the student remains in a four-year program with satisfactory academic progress at college. The maximum scholarship award amount available for tuition and fees is $3,500 per year.
